2002 Interactive Deaggregations
This application computes the deaggregation of the values displayed on the 2002 USGS National Seismic Hazard Mapping Program (NSHMP) Hazard Maps for the conterminous United States and Puerto Rico.
Provide a Site Name and specify its location (in terms of latitude and longitude or by address if your browser supports Google Maps) to begin the process. Specify the time period over which to consider the hazard for deaggregation (Return Period), the Spectral Acceleration (SA) frequency of interest, and indicate the type of Geographic Deaggregations and Stochastic Seismograms that are desired. Links to the following information will be returned:
- A plot of deaggregated distance, magnitude and ground-motion uncertainty for the specified parameters.
- An ascii text file of the hazard matrices, containing, but not limited to, the frequency selected.
- A geographic deaggregation plot may also be specified (for designated frequencies only - see below; if requested by selection of a Geographic Deaggregation option). This is in addition to the plot mentioned above.
- An ascii text file and graph of the seismograms for the modal or mean event (if requested by selection of a Stochastic Seismogram option).
Please read the README file to understand limitations of this application and to ensure valid application results. The README file explains about the input parameters and also describes how the deaggregation is done. Stochastic Seismograms and What is Epsilon? are articles which discuss the theory behind the seismograms.
